You should play with the color balance a little too. I don't have much time today, but here is an alternate attempt...

Nice work, Shaw. I especially like how you got the chin shadow to match his beard. The hands look pretty good. If the fingernails were lightened a little, I think it would look even more realistic. What kind of blur technique did you use on his head? I've found the default blur often too much... the other blur controls are tricky to work, as there are so many considerations. It would be great to have a percentage control the default blur. Incidentally, what is the scene from? Looks like a 1st season episode.
